Which technology utilizes CT imaging and virtual bronchoscopy to create a 3D roadmap to allow access of lung lesions deep in the parenchyma?

• A. ENB (electromagnetic navigational bronchoscopy)
• B. EBUS (endobronchial ultrasound)
• C. Mediastinoscopy
• D. Pleural biopsy

Answer: (A)

Navigation-based bronchoscopy that uses CT-derived imaging to build a 3D roadmap allows reaching deep parenchymal lung lesions. Electromagnetic navigational bronchoscopy uses pre-procedure CT to create a virtual bronchoscopic pathway to the target lesion and then tracks the bronchoscope magnetically in real time to follow that map. This combination of a CT-based virtual route and real-time navigation enables access to peripheral nodules that are beyond the reach of conventional bronchoscopy. It often improves diagnostic yield for deep lung lesions while avoiding more invasive surgical or percutaneous approaches. Endobronchial ultrasound relies on ultrasound visualization of structures adjacent to the airways rather than a CT-based 3D roadmap; mediastinoscopy is a surgical approach to the mediastinum, and a pleural biopsy targets the pleural space, not deep parenchymal lesions.
